1 Claim.

' This invention relates to material handling apparatus and more particularly to a conveyor means suitable for transferring material from one conveyor to another, as in rock crushers and '5 the like. r

In order tosec e large production in rock crusher systemsand other devices of this character, the machines become very heavy and cum- .bersome and even the portable crushers are diflito another. In

cult to move fromone point addition, these machines relativefy oomph-7 cated and employ a large number of parts.

A general objector my invention is to simplify rock crushing machinery and conveyor systems.

Another object of my invention is topr'ovide means for securing a more compact organization of the parts of rock crushers and the like and of conveyor machinery in general. 1 Another general object of my invention is to provide means for readily transferring mate rial from one conveyorto another. Other and further features and objects of the invention will be more apparent to those skilled in the art upon a .consideration'of the accompanying drawing and following specifications.

wherein is disclosed. a single exemplary embodiment oi." the invention, with the understanding,

' however, that such changes may be made therein as fall within the scope of the appended claim,

without departing from the spirit of the invention.

In said drawing:

Figure 1.'is a more or less schematic diagram of a rock crusher'embodying my invention but showing parts of the device in .detail and in section- 1 Figure 2 .is a vertical section of the rotary" drum mechanism taken oh the line 2-: of Fig- 40 Figure 3 is a fragmentary view in -section taken on the line H of Figure 2, and

' Figure 4 is a fragmentary means for supporting and'dniving the rotary drum mechanism.

Referringnow tothedrawing:

Referring now more particularly'to Figure'l,

the main frame of a rock crusher of usual eon-rstruction, except as to the addition of a device constructed according to my invention, is-indicated at 3.. This main irame is supported on .dual wheels llfand front wheels ii. In devices of this character it is the general practice to provide an endless belt conveyor i3 running the length of themachine in the direotion indicated plan view of t e by the arrows. This belt conveyor is adapted to receive material from the loading conveyor l,l and hopper I! and carry it up the conveyor to the front or the machine where it is deposited on a vibrating screen ll.

The lighter, finer screenings drop down to the 5- screens ll and II intothe hopper, and are carried outby the belt-22. The'screens l1, l8 'and II are of increasing fineness and material which will pass through the screen", but is not of such fineness as to pass through the screen-10 It. travels downwardly over the screen I 9 and falls onto the delivery conveyor 23. -Material which will pass through the screen II, but will I not pass through the screen I I; travels downwardly over the screen "and over second screen 24 to 15 drop between the roll crushers It and 21; After passing through the roll crushers 28 and 21 the material falls onto the hopper 2i and is then falls on the inside of the drum conveyor I l The drum conveyor ,has annular sides 42 and Q3 and peripheral band 46' and is preferably pro-' 80 vided with'blades or paddles 41. These paddles 41 are preferably inclined or nonradial so as to form pockets 40 to hold and carry the material discharged from the conveyor belt II; It may. readily be understoodthat material received in the pockets will be carried to a position near- .the top of the drum as the. drum .is rotated, and will be discharged onto the upper level. of the conveyor II so that it may begin its recirculating. movement for further screening, sizing and crushing. I

In devices nowknown to the art. it has been a dimcuit problem to return material from the conveyor II to the conveyor l3; Oiiset. chutes andthelike haveibeen provided for-this purpose, but it is quite apparent that .one or the to partly dismantle the machihe and apparatus when moving it from one point to the other.

By utilizing the drum constructed according to my invention, material may be picked up from the lower conveyor 29 and conveyed'to the upper as conveyor withoutthe necessity of offsetting one or the other of these conveyors. The space required is thus materially decreased and the emciency of the crushing apparatus is improved.

The drum 4| is preferably supported by means of flanged rollers 5| and 52. The drum 4| is provided with annular angles 53 and 54 which stiflen the edges of the drum and serve as tracks to roll. on the rollers 5| and 52. These rollers 5| and 52 are driven -by means of shafts 58 and 51 which are in turn driven by means of bevel gearing 58 and 59. The bevel gears are driven by the cross shaft 6| and this cross shaft is in turn driven from any suitable source of power by the drive shaft 62 and bevel gear 55.

The drum 4| is preferably guided in its upright position by means of a frame 53 having inwardly projecting rollers 84 and 55. These rollers roll on the side walls of the flange members 53 and 54 andhold the drum in upright position.

In order to cut down on the length of the" machine it may be desirable to position the hopper l6 forwardly of the rotary drum.- -If this is done, the conveyer can be shortened by termi nating it at the rear side of said drum. Since machines of this type are rather long and sometimesdiflicult to move, because of their length, I have found that the shortening of this con- Further veyer is of considerable advantage. more, with the use of my drum, I have eliminated the necessity for mounting the main conveyor at the side of the machine, and have, therefore,

considerably reduced the-width of the machine. From the foregoing description, it will be seen that I have provided means for transferring, elevating and reversing the direction of the material treated, with an arrangement which has not only greatly reduced the number of working parts required but has also provided a much more compact arrangement. The apparatus is much of course, apparent that it may be utilized at any point where it is desirable to transfer material from one conveyer to another.

Although I have described a specific embodiment of my invention, it is apparent that the device may be modified. Such modifications may be made without departing from the spirit and scope of my invention as set forth in the appended claim.

I claim as my invention:

In a portable rock crusher, having a receiving hopper at its rear and toward its lower portion, a second hopper at its front and upper portion and an endless conveyor taking material from the first hopper to the second hopper, a vertical transfer wheel located between said hoppers and adjacent the rear hopperand encir-, cling said endless conveyor, and means for delivering crusher aggregate thereto, said vertical transfer wheel operating to deposit such mate rial on the endless conveyor after said conveyor has received material from the first named hopper;
